Carrera subway how do i raise the handle bars on a carrera subway

indications are that the taper lock nut at the bottom of the handle bars has been wound off and fallen into the fork area
remove the bars and tip the bike up side down to get that nut to fall out
put the nut back on the bolt at the bottom of the bar , refit and do the bolt up

If it is an older bike, you loosen the bolt at the top of the handle bar shaft until it is about 1/2 inch raised. Take a hammer and give it a swift bump and it should drop into the shaft. Hold the front tire between your legs and the handle bar should raise up. Re tighten once every thing is lined up. If the bike has front hand breakes these may need to be adjusted.

you cant raise the handle bar but you can add spacers to increase the height.Wish we could be able to raise the handbar

The location of the trunk "handle" is on the left bottom side of the driver's seat where you'll see an image to "lift" the bar to open the trunk which in the front of the car on a Porsche.

You need to loosen the front bolt that holds the handle bars to the front wheel raise it to your desired position and then tighten it again, making sure that the handle bars are at the position you desire them. This will lock them in place so you can ride your bike and not let them fall back down deeper into the front wheel shaft.

No, but a bike shop can assist you in selecting and fitting a stem with a higher rise.

There are two bolts in the center of the handle-bars. One bolt (on some bikes this is actually 4 bolts) is used to clamp the handle-bars to the handle-bar-stem. You can see both ends of this bolt. If you loosen it, you can tip the handle-bars up and down, but not raise them. The other bolt you can only see the head of. Loosen this a couple of turns (don't unscrew it all the way) then give it a tap with a hammer. You will then be able to pull the handle-bar-stem completely out. Do this so that you can see the wedge-shaped nut at the other end of the bolt. You should also see a mark on the stem that indicates how high you can safely raise the stem. Put the stem back in to the desired height and tighten it back up. Good luck.

In order to raise the handle bars, you will need a hex key. Put it into the hex indentation at the top. Turn it left to loosen it. Then raise the handle bars to the desired height.

The stem for the marin is fixed so you'd have to replace it with one that is higher if you wanted to raise the elevation of your handle bars. You can pivot the handle bars for your preferred angle of comfort though. Loosen the 4 screws on the top of the stem and then you can adjust the handle bars to the correct angle that is best for you.
